Question

The median thickness of pads designed for use in aircraft engine mounts is measured. The results in mm are 41.23, 42.11, 41.83, 41.01, 42.68, 41.37, 41.83, 42.67, 40.23, 43.88, 41.43, 41.99, 42.49, 42.03, 41.23, 40.76, 40.50, 41.70, and 41.42

a. State the appropriate hypothesis(ses)

b. Using the appropriate non-parametric test to determine if the median thickness these pads is 41.23 mm at alpha = 0.10

c. Use the large sample approximation to solve this problem also.
